Awesome, camera streaming direct to tracking/telemetry station, relayed to internet, watching a spacecraft orbiting in near real time. As said, awesome.

^ I have a stupid question, can't visualise in my head. How is Apogee increasing whilst lowering Perigee?

Are they simply burning Radial out (sort of perpendicular to prograde) in order to raise Apogee, but to lower Perigee to below 0m they would have to lower their orbital velocity as well?

Or am I so far off the mark it's embarrassing? :D
 
I've experienced it in Kerbal, but couldn't tell you the why or the math. I'm sure we have a rocket scientist here somewhere who can help!
 
I have no idea how they can take an image like the one above and expose correctly for both the dark rocket and the bright flames, unless they've already had time to HDR it in photoshop!
